[PATCH 00/10] Supporting restricted NAND controllers

[Miquel Raynal <miquel.raynal@xxxxxxxxxxx>]

Hello,

The first 6 patches are just miscellaneous changes, that do not bring
functional changes but clarify a few core areas.

Path 7 adds a way to test what the controller ->exec_op()
implementation actually supports and decide to either "pack" the NAND
operations as much as possible, otherwise continue to split operations
as usual.

Patches 8 and 9 use this flag to fallback on packed operations during
ONFI/JEDEC parameter page reads (the idea of these two patches is
imported from a previous series).

Finally, patch 10 does the same in the core, in the read/write_page
helpers.

This series is needed in order to support controllers like Arasan's.

Thanks,
Miquèl
